(a(i))[1]
On Fig. 10.1, circle the diodes that are conducting when point B is positive relative to point A.
(a(ii))[1]
Calculate $V_{\text{MAX}}$, the maximum potential difference across resistor R.
(b)
A capacitor is added to the circuit so that the potential difference across resistor $R$ is smoothed. Fig. 10.2 shows how the potential difference $V$ across resistor $R$ varies with time $t$.
(b(i))[1]
On Fig. 10.1, draw the capacitor symbol and connect it to give smoothing.
(b(ii)1)[1]
State the effect, if any, on the ripple magnitude on $V$ when a capacitor with larger capacitance is used.
(b(ii)2)[1]
State the effect, if any, on the ripple magnitude on $V$ when resistor $R$ has a smaller resistance.
